• Game Technologies: DirectX, XNA, XACT, etc. general use of XNA vertex types?

  I am trying to create some methods to manipulate various parts of the XNA vertex structs. I want to be able to pass all the different vertex types as arguments to these methods. Because they are structs they don't derive from a base class other than ValueType. If I use ValueType as the parameter I don't have access to the propertys of the vertex. Is this a case where refelection would be usefull Can anyone help me find a way to write a method that can access the position property of any type of vertex. I hope I have been clear enough. Thanks. You can do something like that : /// <summary> /// <para> Custom vertex typesfor ground. </para> /// </summary> ...Show All

• Visual FoxPro cryptography failure

  I use _cryptapi class of the _CRYPT class library to encrypt limited amount of information: ids and passwords. They are in a table and the table feeds treeview items on demand. Before appearing in treeview the field values are automatically decrypted. Everything has been working fine until I noticed a problem yesterday. I have done most of development on C: drive but recently began moving the whole project to a G: drive since I set a new OS up on that partition. It is a bootable partition. If the encryption done on C: partition it can only be decrypted on that same partition. On partition G: everything is garbled. If I encrypted an item on G: partition I can decrypt it only here, it will be garbled if I run the application on C: I ch ...Show All

• SQL Server Limiting Results from MDX query

  Is there any way to specify that I only want the last 16 rows of an MDX query Thanks. What I actually need is to have my results only return values that fall within a certain date range. It's kinda complicated. First I need a cumulative running total of hours charged, then after that I need only the last 16 weeks of data. I was thinking of something like this, but it's not working. WITH MEMBER [Measures].[CumulativeTimeCharged] AS 'SUM({NULL:[Date].[Week].CurrentMember},[Time Charged])' SET [SixteenWeeks] AS 'Filter( [Date].[Day].Members, [Date].[Day] >= STRTOMEMBER(@graphStartDate, CONSTRAINED) AND [Date].[Day] <= STRTOMEMBER(@ToDate, CONSTRAINED))' SELECT NON EMPTY { [Measures].[CumulativeTi ...Show All

  HI, all I was working on the following sample which lets you use https transport with Username/Password validation.

What I would really like to know is, how can I set the username/password in code Say, what if I wanted to set the username and password for the database that the service is going to access Thanks for your time in advance. You can use Membership Provider however that is a bit heavy. We put in Custom U/P Validator just for this r ...Show All

• .NET Development deserializing without loading assembly

  Hello! I'm working on plugin framework, where each plugin resides in its own AppDomain. Plugins are configurable. Configuration variables may be different for each plugin, but should be accessible from main application. I guess discovering plugin's config variables via Reflection would cause loading plugin's assembly into main AppDomain, which is what I want to avoid. My question is: is it possible to serialize object defined in assembly "A" loaded into some AppDomain and send it to another AppDomain (as byte[], string or XmlWhatever), and then deserialize it in that AppDomain without loading assembly "A" into it In my current implementation plugins store their configuration variables in Dictionary, thus making configuration via PropertyG ...Show All

• Visual Basic Drop Down Item Mouse Hover

  I am using a context menu in a text box, and have a menu item called 'Quick BOM' - when the user hovers the mouse over this, a drop down menu for 'Quick BOM' opens that is dynamically created from an SQL query that populates this according to the part number in the text box. This all works fine. The next function I want to add is for an event to be called when the user hovers the mouse over the new drop down menu that will allow me to do further analysis of this part number (such as recall a description and place in a label field). There is a DropDownItemClicked event, but what would be most useful is a 'DropDownItemMouseHover' type event. Any suggestions on how to create such an event - the menu contents will change ...Show All
